Pettersson was accused of the murder after an extended investigation by the Swedish police. The original tip fingering Pettersson has been described by some as very dubious.
Pettersson was awarded a seven figure compensation award for defamation by the police and for wrongful imprisonment. He has since made money by selling his tale to newspapers.
Another Christer Pettersson is the founder of SVEROK and one of the authors of the Trygg-Torkel game.
